The Assessment of SpondyloArthritis international Society (ASAS) handbook: a guide to assess spondyloarthritis
TLDR
A comprehensive handbook on the most relevant aspects for the assessments of spondyloarthritis, covering classification criteria, MRI and x rays for sacroiliac joints and the spine, a complete set of all measurements relevant for clinical trials and international recommendations for the management of SpA are provided.
The development of Assessment of SpondyloArthritis international Society classification criteria for axial spondyloarthritis (part II): validation and final selection
TLDR
The new ASAS classification criteria for axial SpA can reliably classify patients for clinical studies and may help rheumatologists in clinical practice in diagnosing axial spondyloarthritis in those with chronic back pain.
Prevalence of spondylarthropathies in HLA-B27 positive and negative blood donors.
TLDR
With a calculated prevalence of 1.9%, spondylarthropathies are among the most frequent rheumatic diseases in the white population and HLA-B27 positive persons carry a 20-fold increased risk of developing SpA.
Ankylosing spondylitis.
TLDR
Treatment with non-steroidal anti-inflammatory agents and physiotherapy remains an important approach to long-term management of patients with ankylosing spondylitis and the new treatment options with tumour necrosis factor blockers seems a breakthrough for patients refractory to conventional treatment.
Defining active sacroiliitis on magnetic resonance imaging (MRI) for classification of axial spondyloarthritis: a consensual approach by the ASAS/OMERACT MRI group
TLDR
For the first time, MRI findings relevant for sacroiliitis have been defined by consensus by a group of rheumatologists and radiologists to help in applying correctly the imaging feature “active sacroiliaitis by MRI” in the new ASAS classification criteria for axial SpA.
The development of Assessment of SpondyloArthritis international Society classification criteria for axial spondyloarthritis (part I): classification of paper patients by expert opinion including
TLDR
The ASAS group has developed candidate criteria for the classification of axial SpA that include patients without radiographic sacroiliitis, and the candidate criteria need to be validated in an independent international study.
Development of an ASAS-endorsed disease activity score (ASDAS) in patients with ankylosing spondylitis
TLDR
The first steps in the development of a new assessment tool of disease activity in ankylosing spondylitis (ASDAS) derived four candidate indices with good face and construct validity, and high discriminant capacity.
ASDAS, a highly discriminatory ASAS-endorsed disease activity score in patients with ankylosing spondylitis
TLDR
The ASDAS is a validated, highly discriminatory instrument for assessing disease activity in AS, including patient-reported outcomes and CRP levels, and outperformed the BASDAI and its single components in all settings.
2010 update of the ASAS/EULAR recommendations for the management of ankylosing spondylitis
This first update of the ASAS/EULAR recommendations on the management of ankylosing spondylitis (AS) is based on the original paper, a systematic review of existing recommendations and the literature
ASAS/EULAR recommendations for the management of ankylosing spondylitis
TLDR
Ten key recommendations for the treatment of ankylosing spondylitis were developed and assessed using a combination of research based evidence and expert consensus.
